Title: Improvements in or relating to luminescent screens

Filed: 1939-01-02
Abstract: 523,359. Luminescent screens. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Jan. 2, 1939, No. 68. Convention date, Dec. 31, 1937. Drawings to Specification. [Class 39 (i)] Luminescent screens for cathode-ray tubes &c. consisting of luminescent material attached to a transparent screen by a binder are constructed to diminish halation. For this purpose :-(a) the luminescent particles may be so attached to the binder that their area of contact therewith is less than 20 per cent. of their total superficial area ; this may be effected by spreading the binder on the screen, allowing it to get tacky and dusting the luminescent material on to it lightly ; or (b) some light absorbing material, such as finely divided carbon or manganese dioxide may be dispersed in the binder to absorb light incident obliquely. To reduce halation by light trapped in the binder layer a binding material may be used, such as boron trioxide, the refraction index of which is less than that of the glass.

Title: Improvements in or relating to refrigeration installations

Abstract: 1,021,538. Refrigerating. STAL REFRIGERATION A.B. Jan. 1, 1965, No. 77/65. Heading F4H. In a refrigeration system having two evaporators 6, 7 connected in parallel, refrigerant from the condenser 2 passes through an expansion valve 3 then through a downpipe 4 to a regulating device 5 which comprises a spring-loaded piston 9 (Fig. 2, not shown) controlling the flow of refrigerant to pipes 10, 11 leading to the evaporators. The piston is stated to maintain the refrigerant pressure in downpipe 4 sufficiently above that in the evaporators to ensure that the latter are supplied equally with refrigerant even when they are at different levels, as may occur when the system is installed on a ship. Expansion valve 3 is controlled in dependence on suction line temperature.

Title: Method and device for pulse shape discrimination
Inventor: LAGUERRE RENE
IPC: G01T1/38
Filed: 1966-01-03
Abstract: 1,083,441. Pulse discriminating circuits. COMMISSARIAT A L'ENERGIE ATOMIQUE. Jan. 3, 1966 [Jan. 12, 1965], No. 93/66. Heading H3T. A method of selecting pulses having predetermined decay rates from a sequence of pulses having one of several predetermined decay rates consists in superimposing on each said pulse a square pulse having a time-duration #, of opposite polarity to said pulses and an amplitude which is equal to the instantaneous value of a " standard " pulse at the time # after its initiation. The superimposition will result in pulses of high decay rate producing signals of the same polarity as the square pulses whereas the pulses having a low decay rate will provide signals of opposite polarity. In Fig. 9, pulses from a scintillation detector are fed via an emitter follower 26 and inverter 28 to a mixer 24. The pulses are also fed via further emitter followers 34, 40 to a lengthening circuit 36 and a gate 38 which is controlled by the output of a monostable circuit 44, triggered by pulses differentiated at 42. Each input pulse thus provides a square pulse at 46 the amplitude of which is determined by circuit 38 and the duration by circuit 44. Each pulse 46 is superimposed on each input pulse (after inversion at 28), the resultant being fed to a polarity sensitive circuit 47 which provides an output indicative of whether the decay rate of each input pulse is greater or less than that of a standard pulse. The output from 47 may be used to operate a coincidence circuit so as to pass pulses having a higher decay rate than the standard pulse or may be used with an anticoincidence circuit arranged to pass pulses of lower decay rate. In Fig. 8 (not shown), two such circuits are used in cascade, being controlled by respective discriminating circuits of the type shown in Fig. 9, each discriminator being by-passed by a delay line. The output may be fed to a multi-channel selector.

Filed: 1980-01-07
Abstract: PURPOSE:To provide high concentration NaOH and high-purity Cl2 with high- current efficiency by a method wherein a fluorine-based cation exchange membrane having carboxyl gp. is placed at anode side, a porous diaphragm separates the membrane from the anode, an aqueous sodium chloride solution is supplied to the intermediate chamber, and HCl gas is supplied to the anode chamber. CONSTITUTION:To electrolyze sodium choride, a fluorine-based cation exchange membrane having carboxyl gp. is placed at the anode side. A porous diaphragm resistance against Cl2 gas is placed between the cation exchange membrane and anode. Aqueous sodium chloride solution is supplied to the intermediate chamber between the cation-exchange membrane and the porous diaphragm. HCl gas or aqueous hydrochloric solution is supplied to the anode chamber. Meanwhile, water or a dilute caustic soda solution is supplied to the cathode chamber to give 25- 43wt% of caustic soda concentration. The process provides high-concentration caustic soda and oxygen-free high-purity Cl2 gas with high current efficiency.

Abstract: PURPOSE:To perform operations for loading a cartridge and taking it out in liaison in the relation of a driving stage by detecting the loading of the cartridge and making a guiding member operating mechanism act so that the cartridge may return to a loading position from a stage. CONSTITUTION:This device is provided with the operating mechanism 17 which allows the guiding member 3 to act by detecting the loading of the cartridge by a detection means at the time of loading the cartridge in a cartridge holder 2, and a switching mechanism 21 which allows the operating mechanism 17 to act so that the cartridge may return to the loading position from the stage 14 with the aid of a switching action. Such restriction that the switching mechanism 21 works after the action of a driving mechanism 15 is stopped is constituted as a circuits, so that the operating mechanism 17 is allowed to work after the mechanism 15 is surely stopped. Thus, a failure that the guiding member 3 works while a recording medium rotates and the cartridge is moved to a takeout position is evaded.

Abstract: A viability test device wherein the viability of a test composition for the determination of an analyte of interest can be determined by simply wetting the device with ordinary water. The viability device can be prepared in three formats: a control or calibrator device, an internal control device and a self indicating device. Unreacted analyte, or an analog thereof, can be incorporated in a limited defined portion of a dried carrier matrix incorporated with a test composition to provide an internal control test device. When wetted with water, a positive optical response, usually color, indicates the test composition can provide a viable test for the analyte. The internal control test device is particularly advantageously used by diabetics in their own homes where a negative test response could be due to the desired control of the user's condition or due to deterioration of a test composition because of unfavourable storage conditions.
